Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-3vgf-8m4q-q4qr. This link is maintained to preserve external references.

Original Description

vm2 versions from 3.11.0 before 3.11.8 fail to protect host TypedArray and ArrayBuffer prototypes from sandbox mutation. Attackers can use prototype-walking primitives to reach and modify host Uint8Array.prototype, %TypedArray%.prototype, and ArrayBuffer.prototype, causing host-created typed arrays to observe attacker-controlled properties after VM.run() returns.
